Standard Issue 10x25 Waterproof Binoculars vs Vortex Optics Diamondback HD 8x42 Binocular

Buy the Standard Issue 10x25 if you want a pocket binocular you can carry every day and don't mind a dimmer, fussier image. Buy the Diamondback HD 8x42 if you want one binocular for serious birding, hunting or low light, and you accept a much bigger, heavier body. The Standard Issue is tiny, IPX7 waterproof and well liked by owners, but its 25 mm lenses and 10 mm eye relief make it hard to use with glasses and weak at dusk. The Diamondback HD has the light gathering, eye relief and included harness of a full-size binocular, and its 4.8 rating from a smaller pool of owners is solid.

• Choose the Standard Issue 10x25 if you want a waterproof binocular that fits in a jacket pocket for hikes, travel and daytime viewing.
• Choose the Diamondback HD if you view birds or wildlife at dawn and dusk, wear glasses, or want one binocular that handles long sessions comfortably.
